Video: Generator Protection

       Generator is the heart of an electrical power system. As it converts mechanical energy into its electrical equivalent, which is further distributed at various voltages. It therefore requires a ''prime mover'' to develop this mechanical power and this can take the form of steam, gas or water turbines or diesel engine.
